"Puerto Rico Declares Public Health Emergency Due to Dengue Spike"

Puerto Rico has declared a public health emergency due to a 140 percent increase in dengue fever cases compared to last year, with 549 cases reported so far. Warmer temperatures and climate change are contributing to the spread of mosquito-borne illnesses globally. Factors such as El Niño, decaying infrastructure, and urban sprawl also exacerbate the situation. The disease, which can be severe and potentially deadly, has affected millions worldwide, with Brazil launching a public vaccination campaign. Governments are implementing various measures to control outbreaks, including public education, insecticide spraying, and deploying new technologies.
